---------------------------------
Summary: Delete temporary files created in YarnClusterDescriptor
Key: FLINK-15134
URL: https://issues.apache.org/jira/browse/FLINK-15134
Project: Flink
Issue Type: Improvement
Components: Client / Job Submission
Reporter: Zili Chen
Assignee: Zili Chen
Fix For: 1.10.0
We create temporary files for storing {{flink-conf}} & {{JobGraph}}. Although
we ask for deleting them on exit, for a long running {{YarnClusterDescriptor}}
it is possibly a resource leak. We can delete the file when they are no longer
used. The delete hook will then silently fail on deletion but it is expected.
